I'm mid-senior level management in a workplace on the periphery of financial services. Senior men come in suits, junior people wear chinos and jumpers (occasionally with a tie). Some of the really senior women wear loose floral dresses and big, loose cardigans internally.
As I've progressed up the career ladder, I've felt a little more at ease with relaxing and wearing what I want to wear. I am a blouse and pencil skirt/skirt suit, fitted dress and jacket, blazer, shirt and cigarette pants on casual days, kind of woman anyway. But I do love a dramatic/theatrical twist. Peplum jackets, a slash of red lipstick, vintage suits/dresses with high, stand-up necklines, or fitted capes, '50s vintage princess or swing coats in bright colours.
My question is: even if I (I like to think I!) always look smart (and colleagues, including senior colleagues, will occasionally comment approvingly on what I wear) and the quality of my work is good/am professional in my demeanour etc. will people think of me differently or be less likely to promote me if I wear things that are a little more interesting than just standard shirt, standard skirt in conservative cuts and colours? I should point out that when I have external meetings, I keep it plain as possible. When I'm giving a talk then I actually prefer to stand out a little.
I love clothes and loving what I wear to work (and I love tailoring and work clothes!) is a huge part of who I am. But if you were my manager, what would you think?
